Totally lost...

I have no idea how to do what they are asking me. Any help greatly accepted. :/ I think I'm on the right track somewhat?

JSONChallenge.java
// JSONObject 'jsonData' was loaded from data.json

String name = jsonData.getString("name");
String publisher = jsonData.getString("publisher");
String language = jsonData.getString("language");

JSONArray jsonBooks = jsonData.getJSONArray("books");

for (int i = 0; i > 2; i++) {
  jsonBooks.getJSONObject(i);

  Log.i("CodeChallenge", jsonBooks.name ", " jsonBooks.getString("pages"));
}
data.json
{
    "name":"Treehouse Book Series",
    "publisher":"Wiley",
    "language":"English",
    "books":[
        {
            "title":"HTML5 Foundations",
            "author":"Matt West",
            "pages":384
        },
        {
            "title":"CSS3 Foundations",
            "author":"Ian Lunn",
            "pages":352
        }
    ]
}

Hi Noah, if you get an opportunity could you please update your post to be more specific about what the issue is you are having trouble with? It will help others on the forums more effectively address the issue for you. Thank you!

//You need to create a new JSONObject inside your for loop 
//and use the newly created JSONObject to log the details
// use the array as the limiting factor in your for loop
for(int i = 0; i < jsonBooks.length(); i++;){

// you tried ---- jsonBooks.getJSONObject(i);
// Try
JSONObject currentObject = jsonBooks.getJSONObject(i)

// then when you log reference currentObject.getString("title") && currentObject.getString("pages")
// instead of jasonBooks

// Your code --- Log.i("CodeChallenge", jsonBooks.name ", " jsonBooks.getString("pages"));

Thank you Micah! Sorry my question was so general. Your code worked spot on, but I just had to replace the && with a +, and it worked just fine.
